How to use a different Wicket expiration/error page for popups and other special pages?

I have a custom error and expiration page in my wicket application. But in some cases, I would like to have them behave differently (e.g. in a popup that should NOT redirect us to home page).

What are the options for the solution? I assume I can read the page parameters in my error/expiration page from the request object (e.g. "errorpage=no"). But how can I add this query parameter to specific pages in optimal way..?

I'm quite certain someone has solved this already so this would be a great opportunity to share a nice solution here..

You could just register a RequestCycleListener that listens "onException" and handles exceptions differently depending on the RequestCycle and otherwise fallback to the default implementation.

(Code based on Wicket 6.6)

        getRequestCycleListeners().add(new AbstractRequestCycleListener() {
        @Override
        public IRequestHandler onException(RequestCycle cycle, Exception ex) {
            if (ex instanceof PageExpiredException) {
                //handle your pageExpiredException...

                if (something) {
                    return new RenderPageRequestHandler(new PageProvider(HomePage.class));
                }

            }

            return super.onException(cycle, ex);
        }
    });
